Iran are shia and the rebels are sunni - two groups that hate each other and have been battling each other throughout the middle east.
The Sunni world is mostly fine with Israel, other than Hamas of course, which is why Hamas had to work with Iran (although it seems like it backfired on Iran)
Egypt, Jordan, UAE, Sudan, Bahrain and the Saudis (through back channels)
It's just a fact, there's absolutely nothing ridiculous about what I said, if anything Sunni regimes are more worried about Iran than israel.
